Description

EQUIPMENT FOR ROTATING AND SLIDING SLIDING SUSPENSION OF PLATE PARTS

Technical field

The present invention relates to a device for pivotally and slidingly suspending plate members supported slidably by means of at least one guide and rotatable about an axis of rotation that is fixed relative to the plate members, comprising a connecting beam which is supported in said guide and which is provided with an elongate groove disposed in substantially the same direction as said guide, and a coupling pin which is arranged non-rotatably on the plate to coincide with the axis of rotation and which is slidably displaceable in said coupling beam groove, the coupling pin being adapted for engaging with the joining beam when the plate is rotated at an angle to the guide.

BACKGROUND OF THE INVENTION

A device from above in the preamble of the description of the stated type is known from patent application WO 94/09238, which describes a sliding-sliding system for suspending window panes, provided with guide wheels for the upper guide and with a support wheel for the lower guide. A groove is formed in the lower guide to guide and move the lower support wheel along the corresponding track. The formation of a lower support wheel with a rounded contact surface engaging the groove edges and a non-rotatable arrangement relative to the pane results in the ability

4 4 4 • 4 · by rotating this wheel when opening the window relative to the groove, causing it to move vertically upwards. This movement is used to insert a pin, which is arranged near the upper guide wheel, into an opening provided in the upper guide. When the pin is inserted into the hole and the lower support wheel is arranged transversely in the guide, the two elements will be locked relative to the longitudinal direction of the guide, which means that the window pane in the open position cannot be folded back or sway.

Without this blockage, due to the weight of the window pane, which causes the tilting moment force due to the window pane hanging in the guide in the plane of the window pane, the upper part of the window pane could be tilted, i.e. sliding the lower part of the pane along the lower guide. This design necessarily requires a large number of components, which makes the solution costly. In addition, during the functional use of this design, there is a great risk that when the window is opened by rotation, the window is rotated upwards to a position in which the pin does not coincide with the corresponding hole, which may result in undesirable damage to the entire window. supporting structures or for breaking a window pane.

Another device of the type known from the prior art in these applications with a joining beam which introduces the preamble of the prior art is described in WO 92/17673 and WO 93/08355. discloses a device provided is rigidly coupled to an upper

83207 (83207a) ·

A guide, and a flattened, chisel-like, rectangular cross-section pin, rigidly coupled to a window pane slidably and rotatably suspended between the upper and lower guides. The connecting beam is provided with an elongate groove which is slightly wider than the smallest dimension of the flattened pin and extends longitudinally, in the direction of the respective guides, over the connecting beam. A plurality of circular recesses are formed along this groove. Each of these circular recesses is adapted to receive a rotatable sleeve provided with a groove that coincides with a groove of the connecting beam in a particular direction of rotation. In the case where the flattened pin is adapted to slide in the groove of the connecting beam through one of its shorter sides in the direction of the respective sliding displacement, the flattened pin extends through said groove of each sleeve. The largest dimension of the flattened pin is slightly smaller than the diameter of the sleeve and the size of the recess. In this state, it is possible to open the pane by rotating the sleeve around the flattened pin and the axis it forms only if the flattened pin rested in a guide within the rotatable sleeve.

The number of components included in this device is large, and very narrow tolerances are necessary for mounting the wiring so that the device performs its function in a sufficiently satisfactory manner.

In conjunction with this design, moreover, if the flattened pin is not aligned precisely with the rotating sleeve, there is a great risk of damaging either the guide or the coupling device as a whole. Moreover, in functional use, since the user uses a large lever to grip and operate the window pane, while the coupling device only operates with very small levers,

83207 (83207a) • · • · As the wiring profile must accommodate all necessary components, great forces are exerted.

The problem, which is common to both the above-described construction, is therefore that if the plate is not in the correct position, there is a risk of damaging the guide or even the coupling device as a whole when rotating it. In addition, these embodiments require narrow mounting tolerances and consist of a large number of components. This results in costly manufacture and complicated installation of window panes and, secondly, in the absence of spatial clearances to eliminate the consequences of slump of the building structure or wear of individual components of the device.

SUMMARY OF THE INVENTION

It is therefore an object of the present invention to overcome the problems described above and to provide a device for pivotally and slidingly suspending the plate members which is simple to manufacture and sufficiently robust.

This object is achieved by means of a device from above in the preamble of the description of the stated type, characterized in that the groove of the connecting beam has an inclined lateral lifting wall; that the joining beam is provided in said inclined side wall with at least one substantially partially circular recess with a central axis substantially parallel to the axis of rotation of the panel; that the coupling pin has a cylindrical surface with a central axis substantially parallel to the axis of rotation of the plate; and that the cylindrical surface of the coupling pin has a bevelled portion

83207 (83207a) with a shape that is substantially the same as that of the side lift side groove of the link beam, the link beam and the link pin being adapted to be displaced relative to each other when the link pin is rotated so that that the inclined side wall of the groove and the tapered portion of the coupling pin abut against each other, and to engage with each other when the cylindrical surface of the coupling pin engages a partially circular recess of the coupling beam during rotation of the plate.

By providing a connecting beam and a connecting pin with cylindrical surfaces which are rotatable relative to each other about a common axis, the proposed device will be very stable and sufficiently robust. In addition, only a very small pivot angle is required to engage the coupling pin of this device with the coupling beam.

The inclined lateral elevated tapered portion allows for the displacement of said cylindrical directions along the respective guides in the connection pin.

the wall and corresponding corresponding alignment to the joining surface support in relation to each other

The edge formed at the intersection between the inclined side lifting wall and the partially circular recess is of such a configuration that the tapered portion of the connecting pin and hence the connecting pin will be upward when attempting to pivot the plate upwards when the connecting pin is not in precise, aligned groove arrangement, forced to move towards the center of the recess. When the coupling pin is rotated, i.e. when the tapered portion abuts the said edge, the surface with the ever-increasing circumference will lean against this edge, resulting in

83207 (83207a) • * due to the existing clearance to necessarily move the coupling pin to a position in which its entire circumference can be introduced into the corresponding recess, that is, increasingly closer to the coupling pin to a position in which the center axis of the coupling pin and center axis the recesses coincide. That is, the device automatically takes into account the misalignment of the panel in the upward-facing position in its functional operation and compensates accordingly for the misalignment. This eliminates the risk of damaging the wiring or some other components of the device due to incorrect turning.

The individual preferred embodiments of the proposed device are evident from the facts set forth in the dependent claims.

DETAILED DESCRIPTION OF THE INVENTION

As can be seen in FIG. 1, the joining beam 100 is provided with an elongate groove 101 which extends along the joining beam 100 and which has a substantially constant width F along its length in the longitudinal direction.

101 has one side wall 102 that is inclined and a second side wall 103 that is straight. Partially circular recesses 104 are formed in the sloped side wall 102 of the groove and are equidistantly spaced apart from each other along the length of the groove 101 (see FIG. 6). The recesses 104 have central axes E which are perpendicular to the direction of the groove and on the base 106 of the groove and whose circular extension represents approximately one third of the total circumference of the circle.

It can be seen from Figures 2 to 5 that the coupling pin 200 has a cylindrical head 201 and a cylindrical shank 202, wherein the diameter D1 of the head 201 is greater than the diameter D2 of the shank 202. The head 201 is formed with a planar angled portion 203, whose shape corresponds to the shape of the inclined side wall 102 of the groove 101 of the joining beam 100. The tapered portion 203 is formed such that the head 201 has a section B that extends in the direction of the central axis C of the joining pin 200 and completely surrounds the diameter D1. In addition, the tapered portion 203 intersects and removes a portion of the upper side 204 of the head 201 of the coupling pin 200 at a distance D from the central axis C at the end thereof through which the coupling pin is mounted. The tapered portion 203 is inclined at an angle gt = 45 ° with respect to the central axis C of the coupling pin 200. The tapered portion 203 is located at one end of the coupling pin 200 while the cylindrical shaft 202 is located at the other end thereof.

As can be seen in FIG. 6, the coupling pin 200, when the coupling pin 200 is oriented so that the tapered portion 203 of its cylindrical head 201 abuts the inclined side wall 102 of the groove 101, slidably slots in the groove 101 of the joining beam 100 Seats

When the coupling pin 200 is moved in the groove 101 so that the coupling pin 200 is aligned with one another of the recesses 104 formed in the coupling beam 100, the coupling pin may rotate about its central axis C. The central axis E of the recesses 104 a the central axis C of the coupling pin 200 is parallel to each other throughout this movement, and the inner cylindrical surface 110 of the partially circular recess 104 thus cooperates with the cylindrical surface 206 of the cylinder head 201 of the coupling pin 200, thereby ensuring very stable engagement.

In the case where the coupling pin 200 is located near the recess 104 and someone is attempting to pivot the coupling pin 200, the tapered portion 203 will cooperate with the edge 105 defined by the common intersection of the inclined side wall 102 and the recess 104 and relocating the cylinder head 201 As a result, movement forces similar to those of the gearwheel are exerted.

The inclined side wall 102 extends upwardly from the base 106 of the groove 101 to the extent that it extends over and beyond the recess 104, thereby providing space for the head portion 201 of the coupling pin 200 with a full cylindrical surface.

The joining beam 100 is further provided with a plate 107, which may be formed either independently of and attached to the joining beam 100, or with the joining beam.

·· in an integral whole. This plate 107 has a lower abutment surface that engages a abutment surface 205 which is due to the fact that the head 201 has a diameter D1 that is larger than the diameter D2 of the shaft 202 defined on the coupling pin 200 by the underside of the head 201. of this surface 205 with the engagement surface of the plate

107 prevents the head 201 of the coupling pin 200 from protruding from the groove 101 in a direction parallel to the central axis C of the coupling pin. In the above-mentioned upwardly directed pivoting of the coupling pin 200 near the recesses 104, the resulting movement forces also in fact produce an active force component whose orientation is parallel to the central axis C of the coupling pin 200.

The plate 107 is arranged and extends such that its edge engages with the shaft 202 of the coupling pin 200 and thereby guides the coupling pin 200, whereby the central axis C of the coupling pin is kept parallel to the central axes E of the recess at all times. The arrangement of this plate 107 may further be supplemented by a corresponding plate (not shown) located on the other side of the elongate groove.

The side wall 103, which is straight or, in other words, perpendicular to the base 106 of the groove 101, may be completely planar, however, it may also be undulated. Individual ripples

108 are disposed in the direction of propagation of the groove 101, resulting in the widening of the groove 101 in areas opposite the end portions of the recess 104 and which represent the narrowest width of the groove 101.

The above-described unwanted pivot blocking device is adapted to be used for pivotal and sliding suspension of panel members, e.g.

As can be seen in FIGS. 9 and 10, the respective number of panes 302, through all four corners of each pan, is slidably hingedly suspended between the upper guide 300 and the lower guide 600. The proposed locking device is arranged in the position of one of the upper corners, however, it is also possible to arrange the device in two corners on one and the same side of the pane or even in all four corners of the pane.

Since it should be possible to open the pane around only one of its side sides, it is in most cases sufficient to provide a locking device only in the upper corner of that side. This is possible due to the fact that the window pane 302 opens in most cases by rotation after it has been moved and brought to one end of the conduit 300, 600. Due to the weight of the window pane 302, the upper portion of the window pane 302 tends to move toward that portion of the window pane. a panel 302 which is rotated outwardly from the conduit 300, 600, while the lower portion of the window pane 302 tends to move in a direction opposite to the exterior of the conduit 300, 600 rotated the upper portion of the window pane 302, or in other words and thus also maintain this position.

The window pane 302 rests with its lower corners 303, 304 on two spherical wheels which travel along the path defined by the lower guide 600. On the upper side, the window pane 302 in the upper guide 300 is suspended by pins 305, 306 extending upwards through a groove formed These pins may be, for example, the stems 202 of the coupling pin 200.

83208 (83208a)

The interlocking beam 100 of the locking device is typically installed in the upper of the two upper and lower conduits 300 between which the pane is suspended. The connecting beam 100, 400 is arranged inside the upper guide

300, while the coupling pin 200 is arranged non-rotatably on the window frame 301.

The window 302 that opens is moved along the guides 300, 600 until the connection pin 200 is brought into alignment with the recess 104 in the connection beam 100. The window 302 can then be opened by rotating it around the coupling pin 200 and thus about the axis of rotation G.

The connection beam and the coupling pin may be formed such that the tapered portion 503 is oriented towards the window frame 301, while the inclined side wall 402 is oriented away from the window frame 301 or vice versa such that the tapered portion 203 is oriented away from the window frame 301, while the inclined side wall 102 is oriented towards the window frame 301 (see, respectively, FIGS. 7 and 8).

As can be seen in FIGS. 7 and 8, the connecting beam 100, 400 is arranged in the upper guide 300 so that said upper guide can be moved up and down in a direction parallel to the center axis of the coupling pin 200, 500.

Since it is equidistant from one another to ensure that the recesses 104 are arranged at a distance A, it is easy to seat the next subsequent coupling pin 200 in the adjacent recess 104. For example, the distance A between the individual recesses 104 may be equal

As a result, the next window pane 302 can simply be displaced by pressing so that its connecting pin 200 abuts the connecting pin 200 adjacent to it. window panes 302.

It will be appreciated from the foregoing that numerous modifications, adaptations, and modifications may be made to the above-described embodiments of the present invention, all of which are within the scope of the claims as set forth in the appended claims.

The coupling beam groove or coupling pin may be formed, for example, with a tapered lead-in section for easier insertion. The tapered section of the coupling pin for insertion is then suitably provided on that portion of the circumference of the head that first comes into contact with the coupling beam, that is, the portion of the circumference that is offset by 90 ° relative to the tapered portion of the head cooperating with the inclined side wall of the coupling beam groove.

In addition, the stem of the coupling pin can be equipped with a telescopic function to replace the vertical displacement of the coupling beam in the guide.

According to another embodiment (not shown), the inclined lateral groove side wall is not planar, but has a more complex shape configuration but nevertheless has a section that is substantially planar and inclined at an angle substantially the same as the planar inclined side wall surface of the preferred embodiment. .

Furthermore, in addition, the side wall 102a may be inclined
